 Spring Security provides you with a very flexible framework for your authentication and authorization requirements, but there are many other considerations for building a secure application that are outside its scope.
 Web applications are vulnerable to all kinds of attacks which you should be familiar with, preferably before you start development so you can design and code with them in mind from the beginning.

 The most common reason for this is that your browser has cached the page and you are seeing a copy which is being retrieved from the browsers cache.
 Verify this by checking whether the browser is actually sending the request (check your server access logs, the debug log or use a suitable browser debugging plugin such as "Tamper Data" for Firefox).

 Sessions are maintained either by exchanging a session cookie or by adding a `jsessionid` parameter to URLs (this happens automatically if you are using JSTL to output URLs, or if you call `HttpServletResponse.encodeUrl` on URLs (before a redirect, for example). If clients have cookies disabled, and you are not rewriting URLs to include the `jsessionid`, then the session will be lost.
 Note that the use of cookies is preferred for security reasons, as it does not expose the session information in the URL.
